Ios 呼叫套件拒绝入站呼叫（目标-C）

我正在使用CallKit开发一个VOIP应用程序（我们称之为SampleApp），我正在努力解决一个问题

我可以使用CallKit以似乎正常工作的方式回答入站SampleApp调用。但是，当我拒绝一个调用时，调用仍然被实例化，这是不正确的行为

根据我的理解，我需要根据呼叫是否被接受和拒绝得到一个布尔值，然后用它来决定电话控制器是否接听来电

这是我的第一个问题，我已经阅读了堆栈溢出指南，但是如果我做错了什么，请告诉我

但是，当我拒绝一个调用时，该调用无论如何都会被实例化，这 这是不正确的行为

不清楚您在这里的代码中试图做什么。您总是呼叫

[自我应答呼叫]

（我们没有看到要执行的代码，但我假设它会向您的应用程序逻辑和后端报告用户已应答呼叫）就在

[\pDelegate reportIncomingCall:…]

之后，因此您似乎假设用户已决定应答，甚至在用户做任何事情之前

相反，你应该告诉你的应用程序逻辑和你的后端，用户已经接听了电话，只有在你的

-provider:performAnswerCallAction:

方法中，并且在你的

-provider:performEndCallAction:

中，告诉你的应用程序逻辑和后端，用户已经拒绝了呼叫（如果是来电）

以下是基于@user102008建议的解决方案，该建议实现了我想要实现的目标

我将应答传入呼叫的责任转移到提供者代理而不是phone view controller，后者调用应答呼叫或结束呼叫方法，具体取决于其提供者方法中的呼叫是被接受还是被拒绝

在

provider:performAnswerCallAction:

中，您是否尝试调用

[action fail]

而不是

fulfillWithDateConnected:

？@davewston感谢您的评论。我尝试了你的建议，但似乎没有效果。在

提供程序：PerformancesWerCallAction:

中，你是否尝试调用

[操作失败]

，而不是

使用DateConnected:

实现？@Davewston感谢您的评论。我试过你的建议，但似乎没有效果。你的评论使我意识到我在倒退。My PhoneViewController（PVC）应接收呼叫，并将其报告给ProviderDelegate，并且该代理应在其自己的PerformancesWerCallAction和PerformanceCallAction中调用PVC的AnswerInMingCall方法。您的评论使我意识到我正在倒退。My PhoneViewController（PVC）应接收呼叫，并将其报告给ProviderDelegate，并且该代理应在其自己的PerformanceWerCallAction和PerformanceCallAction中调用PVC的AnswerInMingCall方法。
